PERMUTATIoN-LOCK.

SPECIFIGATION forming part of 'Letters'Patent No. 659,627, dated October 9, 1900. applicati@ med March 5, 1900. 'Serial Nofmo. (No model.)

To @ZZ whom, it may concern:

Be it known that I, GEORGE A. REDDICK, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee,have invented certain new and useful improvements in Permutation-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

rllhis invention relates to permutation or disk-controlled locks. i

' The object of the invention is to produce a lock in Which the permutation disks or tumblers are supported in aretaining-chamber which slides with the bolt and in which the disks are held against rotation or other movement, except a sliding movement, whenever the bolt is not fully shot to locked position. By such construction a very simple permutation-lock may be made, and much annoyance,

-dne to displacement of disks by turningthe handle when the lock is open,may be avoided.

Figure 1 is a plan or partial section of the lock with cover or casing-top removed and showing bolt in locked position; Fig. 2, a similar plan with bolt open and disks and holder in position; Fig. 3, a central longitudinal section of the lock in open position. Parts of the door and jamb are indicated in Figs. 1, 2, and 3. 1Eig. 4 is a perspective of three permutation tnmblers or disks. Fig. 5 is a plan of the disk ring and bolt.

The numeral 1 indicates the lock-casing. This is of any usual construction for either a inortise, rim, or extension lock. 'lhe casing may be cast from metal or otherwise constructed and may be integral with or separate from a bolt-housing 2. v Within the chamber 1 there is a disk chamber or ring 3, which chamber or ring is attached tdthe bolt 4, said bolt extending in the housing 2. The ring 3 is open or slotted at 33. The slotted ring 3 ineloses the disks of the permutation device and forms ahousing therefor.

The knob or handle 5 has a spindle 6,Which extends through a slot 7 in the casing. The spindle 6 has one of the disks, as 20, attached to the inner end thereof by a screw or other device, so that said disk will turn with the The disk 2O is within the chamber move bolt.

3, and iby sliding the handle 5 and 6 in the direction of the length ot' the or ring spindle .slot7 the disk willmove with the spindle,

engagement with the ring 3 will 55 and by its cause the bolt 4 to slide in the same direction and to the same distance as spindle 6. -Disk 20 is slotted in radial direction, as shown at 21. The disk must be turned to such position that the slot 2l will pillar or stop 19 in the casing before the bolt can slide to open position. The slot-disk 2O,A moving the ring 3 with it, will of course 4, which is attached tothe. ring. Any additional for the purpose of making any desirable combination. Three disks are shown, the disks Band 24 being held on a hub 25, which is supported by a spider or bar 26. The spider or bar 26 extends across the ring resting in notches in said ring, so that the disks. are supported from the bar instead of bearing directly against ring3. All the disks are to' be of such size as to turn easily-in the ring or chamber 3. ted at 27 and 28. Each disk is provided with an operating pin or screw 30, and these pins may be screws which engage in threaded holes in the disks, and the change of position of one or more of these pins or screws the combination of the lock, as usual in locks of this general character. The spindle 6 carries a dial 14, which turns with the spindle,

and by its position relative to an index-plate` indicates the necessary rotations ofthe spin- 85 die to Work the combination in usual manner. When disks 20, 22, and 24 are turned so that the slots or notches are in line with each other and in line with the ,notch 33 in the ring or chamber 3, said ring 3 may be 9o slid bodily within the casing, carrying the disks along in either direction as far as the pillar 19 by its entrance into the notches will permit, and when Said ring' and disks are moved along so as to have the notches 21, 27, 9'5.

and 28 embrace said pillar 19 the disks can.-

, :not be rotated, being held against rotation by such pillar. When the bolt 4 is shot to locked position in keeper 40, the disks may be turned by turning the spindle. of the disks is turned far enough so that its notch cannot slide along toembracethe pilmove over the fixed 6o number of disks 'may be used 65 3,' its ends 7o Disks 22 and 24 are slot- 75 changes 80 As soon as any one zoo lar 19 the bolt is locked and the combination must be Worked to bring the notches again in line, so that the bolt may be opened.

To permit of openingr the lock should the combination be lost, it is advisable to have a small hole 45 in the rear facing 46 of the lock, said hole having a swinging.r cover 39. A small key or tool can be entered through this opening, and by working or turning the spindle in one direction and the other until this tool or key can enter the slots 21 27 28 the disks may be brought to such position that the bolt maybe slid. This of course requires either that thedoor be open or that there be collusion from both sides of the door', but is a provision against accidents.

. ing the key 50 The spindle 6 may be adapted for use with doors of diteringthickness by an extensible ortelescopic piece, as is common. In fact, the lock may be adapted for most uses `to which locks with sliding bolts are' applied, the advantages over most perm utation-locks beingin the simplicity of construction'and the non-1iabi1ityof disarrangement while the bolt is Withdrawn.

The spindle 6 is held to disk 20 by wedge or key' 50, which enters a slot in the spindle,`

or by other convenient mechanism. Spindle 6 has a ring 55 attached, and on this ringe pin 56 projects backward in position tochter one of the holes 57 in the disk 20. By loosenthe spindle 6 can be turned part way around, t-hus entering pin 56 into 'a new hole 57, and so changing theceinbnation.

Thus an additional way of changing the cor'nbination is provided.

The ring' 3, rigidly c'onnectedtothe bolt 4, serves asa housing for the perm mation-disks, and, in connection with the bar er spider 26,-

incloses said disks, although the disk nearest the knob is not supported bythe spider, hut by the knob-spindle.

What I claim is* l. In a permutation-lock, the bolt, a slotted ring connected tothe bolt and forminga housing for the disks of the permutation device, a casing for the bolt and for the slotted ring, a fixed pillar witliinv the casing in line of movement of the slot in the slotted ring, a\ spindle' connect-ed to Aslotted disks Within the slotted ring, as described, and a cross-bar connected to the slotted ring and supporting one of the disks remote from the spindle.

2. In a permutation-lock, the bolt, a slotted ring permanently connected thereto, a spider connected to said ring by resting in notchesl permutatiomdisks within saine being supported by in the edge thereof, the ring,`one of the the spider, a spindle connected to the disk at Vthe side opposite^the spider, and a pillar in path of movement ofthe at lhefopposite sideof the all combined substantially lbined substantially as described.

In testimony whereof I ax Imy signature in presence of two witnesses. t
